ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

The capabilities of new methods of fusion alpha-particle diagnostics based on nuclear reactions are discussed. Particularly, the resonant capture reactions between confined fast alpha particles and low-Z artificial impurities in the plasma is examined. In this case, the intensity of the decay gamma rays is proportional to the alpha-particle concentration at resonance energy. Another method is based on Doppler shape analysis of the 4.44-MeV gamma-ray spectra from the 9Be(α, n1γ)12C reaction. Results of an in-beam study of this diagnostic reaction are given. Some questions concerning the gamma spectrometer, a collimator, and a radiation shield are discussed. Estimates of the reaction rates and signal values in the Tokamak Fusion Test Reactor, T-14, Compact Ignition Tokamak (CIT), and International Thermonuclear Experimental Reactor (ITER) are presented. In conclusion, the use of gamma spectroscopy in the diagnostics fusion protons in deuterium-deuterium plasma is examined.
